Background: The No Germs on Me (NGoM) Social Marketing Campaign to promote handwashing with soap to reduce high rates of infection among children living in remote Australian Aboriginal communities has been ongoing since 2007. Recently three new television commercials were developed as an extension of the NGoM program. This paper reports on the mass media component of this program, trialling an evaluation design informed by the Theory of Planned Behaviour (TPB).Methods: A survey questionnaire taking an ecological approach and based on the principals and constructs of the TPB was developed. Surveys were completed in six discrete Aboriginal communities immediately before and on completion of four weeks intensive televising of the three new commercials.Results: Across the six communities access in the home to a television that worked ranged from 49 to 83 % (n = 415). Seventy-seven per cent (n = 319) of participants reported having seen one or more of the new commercials. Levels of acceptability and comprehension of the content of the commercials was high (97 % n = 308). Seventy-five per cent (n = 651) of participants reported they would buy more soap, toilet paper and facial tissues if these were not so expensive in their communities. For TPB constructs demonstrated to have good internal reliability the findings were mixed and these need to be interpreted with caution due to limitations in the study design.Conclusions: Cultural, social-economic and physical barriers in remote communities make it challenging to promote adults and children wash their hands with soap and maintain clean faces such that these behaviours become habit. Low levels of access to a television in the home illustrate the extreme level of disadvantage experienced in these communities. Highlighting that social marketing programs have the potential to increase disadvantage if expensive items such as television sets are needed to gain access to information. This trial of a theory informed evaluation design allowed for new and rich information to be obtained about community members' beliefs, attitudes and intentions towards teaching and assisting children so safe hygiene behaviours become habit. Findings will support an evidence-based approach is taken to plan future NGoM program activities. [ABSTRACT FROM AUTHOR]

Purpose: Different health state utility (HSU) instruments produce different utilities for the same individuals, thereby compromising the intended comparability of economic evaluations of health care interventions. When developing crosswalks, previous studies have indicated nonlinear relationships. This paper inquires into the degree of nonlinearity across the four most widely used HSU-instruments and proposes exchange rates that differ depending on the severity levels of the health state utility scale.Methods: Overall, 7933 respondents from six countries, 1760 in a non-diagnosed healthy group and 6173 in seven disease groups, reported their health states using four different instruments: EQ-5D-5L, SF-6D, HUI-3 and 15D. Quantile regressions investigate the degree of nonlinear relationships between these instruments. To compare the instruments across different disease severities, we split the health state utility scale into utility intervals with 0.2 successive decrements in utility starting from perfect health at 1.00. Exchange rates (ERs) are calculated as the mean utility difference between two utility intervals on one HSU-instrument divided by the difference in mean utility on another HSU-instrument.Results: Quantile regressions reveal significant nonlinear relationships across all four HSU-instruments. The degrees of nonlinearities differ, with a maximum degree of difference in the coefficients along the health state utility scale of 3.34 when SF-6D is regressed on EQ-5D. At the lower end of the health state utility scale, the exchange rate from SF-6D to EQ-5D is 2.11, whilst at the upper end it is 0.38.Conclusion: Comparisons at different utility levels illustrate the fallacy of using linear functions as crosswalks between HSU-instruments. The existence of nonlinear relationships between different HSU-instruments suggests that level-specific exchange rates should be used when converting a change in utility on the instrument used, onto a corresponding utility change had another instrument been used. Accounting for nonlinearities will increase the validity of the comparison for decision makers when faced with a choice between interventions whose calculations of QALY gains have been based on different HSU-instruments.

Background: Surveys are commonly used in health research to assess patient satisfaction with hospital care. Achieving an adequate response rate, in the face of declining trends over time, threatens the quality and reliability of survey results. This paper evaluates a strategy to increase the response rate in a postal satisfaction survey with women who had recently given birth.Methods: A sample of 2048 Australian women who had recently given birth at seven maternity units in New South Wales were invited to participate in a postal survey about their recent experiences with maternity care. The study design included a randomised controlled trial that tested two types of pre-notification letter (with or without the option of opting out of the survey). The study also explored the acceptability of a request for consent to link survey data with existing routinely collected health data (omitting the latter data items from the survey reduced survey length and participant burden). This consent was requested of all women.Results: The survey had an overall response rate of 46% (913 completed surveys returned, total sample 1989). Women receiving the pre-notification letter with the option of opting out of the survey were more likely to actively decline to participate than women receiving the letter without this option, although the overall numbers of women declining were small (27 versus 12). Letter type was not significantly associated with the return of a completed survey. Among women who completed the survey, 97% gave consent to link their survey data with existing health data.Conclusions: The two types of pre-notification letters used in our study did not influence the survey response rate. However, seeking consent for record linkage was highly acceptable to women who completed the survey, and represents an important strategy to add to the arsenal for designing and implementing effective surveys. In addition to aspects of survey design, future research should explore how to more effectively influence personal constructs that contribute to the decision to participate in surveys.
